OMB Control No. 2060-0722
Approval expires 08/31/2021
Background
CenterPoint Energy, Inc., headquartered in Houston, Texas, is a domestic energy delivery company
that includes electric transmission & distribution, natural gas distribution, and energy services
operations. With more than 7,400 employees, CenterPoint Energy and its predecessor companies
have been in business for more than 140 years. As a long time member (1997) of the EPA Natural
Gas STAR Program, CenterPoint Energy has achieved cumulative methane emission reductions of
over 170,000 million cubic feet (Mcf). CenterPoint Energy has found the STAR Program an
important tool to move forward with system improvements not only to ensure system safety but to
minimize methane emissions.
With EPA's Methane Challenge, CenterPoint Energy intends to participate in the Best Management
Practice (BMP) Commitment option for Cast Iron and Bare Steel replacement. As a founding
member of the Methane Challenge Program, CenterPoint Energy will continue to implement
technologies and practices to reduce emissions of methane.

CenterPoint Energy Historical Fact Sheet
Historical Highlights
Identify and Rehabilitate Leaky Distribution Pipe
Since joining the EPA Natural Gas STAR Program in 1997, nearly 55% of the over 170,000 Mcf cumulative
methane emission reduction has been achieved by completing leak surveys and repairing identified leaks.
Inject Blowdown Gas Into Low Pressure Mains
The decision whether or not to lower pipeline pressure prior to replacement of pipe is determined on a case-
by-case basis by Engineering staff. Factors that are taken into consideration include (1) location of the pipe,
(2) if the area has adequate backfeed, and (3) if there is a lower pressure distribution system available to
bleed the gas into. Over 24% of the cumulative methane emission reduction has been achieved by
incorporating this practice.
Identify and Rehabilitate High-Bleed Pneumatic Devices
The replacement, retrofit, and maintenance of high-bleed pneumatic devices has contributed to 20% of the
cumulative methane emission reduction accomplished since 1997.
